AI Technical Summary
Existing universal joint assemblies have overly complex and costly sealing structures, or they are unreliable, heavy, and unsightly, failing to effectively prevent the entry of foreign objects such as dirt and sand, leading to wear and reliability issues.
The dust cover structure, including corrugated or fabric-laid rubber dust covers, is used to secure the dust cover with a retaining ring and a sealing locking device to ensure reliable sealing. The dust cover also stores grease for lubrication and prevents foreign objects from entering.
It significantly improves the product life and reliability of the cross shaft universal joint assembly. It has a simple, compact, lightweight, and reliable sealing structure and is widely used in the high lift system of domestic transport aircraft.
